WHEEL-LOCK.

Application filed November 8 1919. sflai No. 336,554.

' To add whom it may concern Be it known that I, CHARL S E. THOMP- SON, a citizen of the UnitedjStates, and'a resident of the city of New York, borough of Manhattan, in the countyof New York and State of New York, have invented-a new and Improved lVheel-Lock, of which the following is a full, clear, and exact description.

This invention relates to improvements in wheel locks, an obj ect of the invention being to provide'a wheel lock which constitutes a chock and which is adapted to be secured around the tire and rim of a wheel and prevent turning movement of the wheel.

A further object is to provide improved means for locking the device in position on a wheel.

A further object is to provide a locking device which dispenses with the n'ecessityfor a key and which cannot be operated exceptby a person having knowledge of the pecul iar movements necessary to release the device.

lVith these and other objects in view the invention consists in certain novel features of construction, and combinations and arrangements of parts, as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawingsf Figure 1 is a view in elevation illustrating my improved device in position on a wheel;

F ig. 2 is an enlarged view in section on the line 22 of Fig. 1, the wheel being omitted; 7

Fig.3 is a on the line 3-3 of Fig. 2 showing the looking device in its normal'position; and

. Fig. 41S a view similar to Fig. 3 showing the locking device in its releasing position.

1 represents a wheel, such as an ordinary automobile wheel, and 2 is my improved locking device which is provided with an enlargement 3 at its outer end constituting a chock to prevent turning movement of the wheel. The body portion of the device'2 is in the form of a yoke 4 having two members 5 and 6 hingedly connected thereto. These members 5 and 6 and the yoke 4 are con structed to receive hinged pins 7 so that the members 5 and 6 can swing outwardly to release the device from the wheel, as occasion may require.

The members 5 and 6 are of angular form fragmentary view in section Specification of Letters Patent.- pam t g pt 0 and an openwork frame 17 is secured to the member 5 and is adapted to engage the rim of the wheel; This frame 17 will be shaped in accordance with the 'crosssectional conin which a locking pin 9 is mounted. A knob or finger hold 10 is secured on the outer end of the pin'9 and a disk 11 and a locking dog 12 are secured on the inner end of the pin 9. The locking dog 12 is of general hook shape and is adapted to engage a locking stud 13 on the member 5; When the parts are in locking position, the disk 11 extends across the meeting edges of the members 5 and 6, as clearly shown in Fig. 3.

A lug 14 is fixed to the inner face of member-6 and is located adjacent the periphery of the disk 11. This disk 11 is provided in its periphery with a plurality of notches 15, any of which are adapted to receive the lug 14 but are not of a sufficient length to allow the locking pin 9 to move far enough in the slot 8 to position the disk 11 to one side of the meeting edges of the members 5 and 6. A relatively deep notch 16 is provided in the disk 11 which is of suflicient length to allow the disk 11 to be moved laterally when this notch 16 is in alinement with the lug 14. Hence, while it is possible to turn the disk by means of the knob or finger hold 10 so as to position the locking dog 12 out of engagement with the stud 13,

it is difiicult for any one who does not knowthe secret to register the proper notch with the lug14 to allow the pin 9 to be moved laterally in the slot 8 'far enough to position the disk llto one side of the meeting edgesof the members 5 and 6 to release them from locked position,. as indicated in Fig. 4. In other words, besides moving the dog 12 out of locked engagement, it is necessary to move the disk and this movement of the disk can only be brought about when the notch 16 is in alinement with the lug 14. This notch 16 can be located at different. points on the disk so that only the owner of the car will know just how to move the knob 10 to permit a release.

- This locking device dispenses With the necessity for any key Which may be lost and therefore give the owner of the car consider able annoyance.

Various slight changes may be made in the general form and arrangement of parts described ithout departing from the in-' scope of the appended claims.

I claim:

1. A device of the character stated, comprising a yoke, an enlargement on the yoke, a pair of angular members hingedly connected to the yoke, one of said members having a transversely extending slot there in, a locking pin projecting through the slot, a knob on the outer end ofthe pin, a disk and a locking dog on the inner end of the pin, said disk and dog both adapted to project across the meeting edges of thememprising a yoke, an enlargement on the yoke,

a pair of angular members hingedly connected to the yoke, one of said members having a transversely extending slot therein, a locking pin projecting through the slot, a knob on the outer end of the pin, a disk and a locking dog on the inner end of the pin, said disk and dog both adapted to project across the meeting edges of the members, a lug on one of the members, said disk having a plurality of relatively shallow notches in its periphery, and asingle relatively deep notch, all of said notches adapted to register with the said lug, but the deeper notch only being of sufficient depth to permit the disk to be moved laterally across the meeting edges of said members.
